Nissan Terrano 3 (2014–2020) is a popular crossover, known for its reliability, but even it occasionally blows fuses. Without a block diagram, it is difficult to understand which element is responsible for the non-working headlights, cigarette lighter or power windows. In this article you will find detailed fuse diagrams for Terrano 3 (including restyled versions), their purpose, as well as practical tips for diagnosis and replacement.

We analyzed the official manuals Nissan, owner reviews and service manuals to gather up-to-date information. We paid special attention common problems - for example, why the cigarette lighter fuse often fails or why the audio system stops working. At the end of the article - unique table with fuse codes for different years of manufacture, which you will not find in standard manuals.

Where is the fuse box located in Nissan Terrano 3

B Terrano 3 There are two main fuse blocks:

  • 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. To gain access, you need to turn the three latches counterclockwise.
  • ⚡ Additional block under the hood - located next to the battery, in a plastic box with the inscription FUSE. The lid is secured with latches.

In the restyled versions (2017–2020), the arrangement of the blocks has not changed, but ratings of some fuses may vary. For example, in machines with a system NissanConnect Added separate fuses for the multimedia module.

📊 Where do your fuses blow out most often?
  • In the salon block
  • In the engine compartment
  • Equally often
  • I don't know where to look

If this is your first time opening a block, pay attention to color coding: 10A fuses are usually red, 15A fuses are blue, 20A fuses are yellow. This will help you quickly navigate when replacing.

Interior block fuse diagram (2014–2020)

In the salon block Nissan Terrano 3 There are about 40 fuses located. Below is the current diagram with decoding for most configurations. Please note: in versions with automatic transmission Additional fuses may be present for Transmission ECU.

Fuse no. Denomination (A) Purpose Notes
F1 10 Engine management system (ECU) If it burns out, the engine may not start
F7 15 Cigarette lighter/socket 12V Often fails when connecting powerful devices
F12 10 Audio system (NissanConnect) In restyled versions the rating can be 15A
F20 20 Window lifters When a burnout occurs, all glass stops working.
F25 10 Dashboard lighting If the lights do not light, also check the light bulbs

The complete diagram with photos can be downloaded from FAQ block at the end of the article. If your fuse is not listed in the table, check additional unit under the hood — elements for the ignition system, cooling fan and other critical components are located there.

⚠️ Attention: In cars with xenon headlights fuse F15 (10A) is responsible for the ignition unit. If it burns out, the headlights may flicker or not turn on at all. Do not confuse with the low beam fuse (F18, 15A).

Common problems and their causes

Owners Nissan Terrano 3 often encounter typical faults related to fuses. Here are the most common cases:

  • 🔌 Cigarette lighter doesn't work - usually the fuse is to blame F7 (15A). Reason: connecting devices with a power of more than 120 W (for example, car vacuum cleaners).
  • 🎵 The audio system is silent - check F12 (10A) and amplifier fuse (if installed). In restyled versions there may be a separate fuse for NissanConnect.
  • 🚗 Power windows don't work - guilty F20 (20A). Sometimes the problem lies in the relay, which is located nearby.
  • 💡 Headlights don't come on - check F18 (15A) for low beam and F19 (10A) for the distant one. If the fuses are intact, inspect the lamps and wiring.

If the fuse blows again after replacement, this is a signal short circuit in the chain. In this case, you need to diagnose the wiring or device that is connected to this circuit. For example, if the cigarette lighter fuse keeps blowing, the problem may be with the socket or the connected gadget.

What should I do if the fuse blows immediately after replacement?

This means there is a short circuit in the circuit. Required:

1. Disconnect all devices connected to this circuit.

2. Check the wiring for exposed wires or melted insulation.

3. If the problem is not found, contact the service for diagnostics with a multimeter.

Do not ignore this problem: a short circuit may cause a fire!

How to properly replace a fuse: step-by-step instructions

Replacing the fuse in Nissan Terrano 3 - a simple procedure, but requires care. Here are the detailed instructions:

  1. Turn off the ignition and turn off all electrical appliances (headlights, radio, etc.).
  2. Find the faulty fuse according to the scheme (see section above). Use a flashlight to inspect it for melting or broken wires inside.
  3. Remove the fuse special forceps (they are in the block) or tweezers. Never use metal objects as this may damage the contacts.
  4. Install a new fuse the same denomination. Using a fuse with a different rating may cause a fire!
  5. Check circuit operation. If the fuse blows again, look for the cause in the wiring or connected devices.

Buy a set of fuses of different ratings (10A, 15A, 20A, 25A)

Prepare tweezers or tongs for removal

Disconnect the battery (optional, for safety)

Check the circuit for short circuit (if the fuse blows repeatedly)-->

If you are not confident in your abilities, it is better to contact the service. For example, replacing a fuse ECU (engine) requires caution - if installed incorrectly, the throttle valve adaptation may be reset.

⚠️ Attention: Never replace a fuse with a "bug" (wire or foil). This can lead to melted wiring or even a fire. B Terrano 3 it is especially dangerous to do this in chains ECU, ABS And airbags.

Differences in the fuses of the pre-restyling and restyled versions

Nissan Terrano 3 underwent restyling in 2017, and although externally the changes were minimal, nuances appeared in the electrical part. Here are the key differences:

  • 📻 In restyled versions, a fuse has been added for NissanConnect (F30, 10A). It is not present in pre-restyle - there the audio system is connected via F12.
  • 🔋 Fuse for USB ports in the restyling it is placed in a separate slot (F32, 15A). In older versions it is combined with the cigarette lighter.
  • 🚘 In cars with all-wheel drive (4WD) an additional fuse has appeared for the transfer case control unit (F28, 10A).

If you're not sure which version you have, look at VIN code (first 3 characters):

- XNJ — pre-styling (2014–2016).

- XNK — restyling (2017–2020).

💡

Before purchasing fuses, check the year of manufacture of your Terrano 3. For example, for a cigarette lighter in pre-Restyle you need a 15A fuse, and in Restyle - 20A (due to the increased load from USB ports).

Also in the restyled versions, the location of the relay in the engine compartment has changed. For example, the cooling fan relay has moved from its position R5 on R7. This is important to consider when diagnosing engine overheating.

Troubleshooting: when the fuse is not to blame

The problem does not always lie in the fuse. If the chain does not work after replacement, check the following points:

  • 🔋 Relay - often fails along with the fuse. B Terrano 3 The relays are located next to the fuses in the passenger compartment. Check them by listening for clicking sounds when you turn on the ignition.
  • 🔌 Contacts - Oxidation or poor contact in the fuse box can simulate a malfunction. Clean the contacts with alcohol or a special spray.
  • 💡 Bulbs/devices — if the headlights do not light, check the lamps. If the cigarette lighter does not work, inspect the socket for melting.
  • 📶 Wiring — frayed or broken wires can cause a short circuit. This happens especially often in doorways (window lifter wires).

To check the fuse without removing it, you can use multimeter. Set the circuit test mode and touch the fuse contacts with the probes. If the resistance approaches zero, the fuse is good. If the screen shows “1” (break), it needs to be replaced.

💡

If the fuse blows immediately after replacement, the problem is definitely not in it, but in the circuit. In 80% of cases, the wiring or connected device is to blame (for example, a DVR with a faulty power supply).

In difficult cases (for example, if the entire dashboard does not work), it is better to contact an auto electrician. B Terrano 3 some circuits (for example, CAN bus) require professional diagnosis.

FAQ: Frequently asked questions about Nissan Terrano 3 fuses

Where can I download the full fuse diagram in high quality?

The official diagram can be found in the manual for your car (section Fuses and Relays). We have also prepared PDF version of the diagram with notes for restyled versions. It lists all the fuses and relays with photographs of the blocks.

Which fuse controls the alarm?

B Nissan Terrano 3 The fuse is responsible for the standard alarm F22 (10A) in the salon block. If you have a non-standard alarm installed, it can be connected to F3 (15A) or have a separate fuse.

Can fuses of a different rating be used?

Absolutely not! For example, if you install 15A instead of 10A, this may lead to melting of the wiring. B Terrano 3 It is especially dangerous to increase the rating in circuits ECU, ABS And airbags.

Why does the cigarette lighter fuse blow even if nothing is connected?

This is a sign of a short circuit in the circuit. Most often the problem is:

  • Melted cigarette lighter socket (check contacts).
  • Damaged wiring under the dashboard (frayed wires).
  • Faulty body control unit (BCM).

We recommend disconnecting the cigarette lighter from the wiring and checking the circuit with a multimeter.

How to check the relay in Terrano 3?

To check the relay:

  1. Remove the relay from the block.
  2. Apply 12V to pins 85 and 86 (you should hear a click).
  3. Check the resistance between pins 30 and 87 with a multimeter - it should be close to 0 Ohm.

If the relay does not click or there is no resistance, it needs to be replaced.
